Essbase中MDX成员拼接问题：新手求助完善MDX查询

Hey there, let's work through your MDX query problem since you're new to Essbase and MDX. Your current code has a messy stack of nested CROSSJOIN functions, it's unfinished (your Scenario set cuts off mid-way), and it's hard to maintain—totally understandable when you're just starting out!

First, Let's Clean Up the Nested Crossjoins #

The core task here is creating a Cartesian product (all possible combinations) of members across multiple dimensions, which is exactly what CROSSJOIN does. But nested CROSSJOIN calls get unreadable fast. Here's a cleaned-up, complete version of your query with proper indentation to keep things clear:

SELECT 
  {([Version].[FINAL])} ON COLUMNS,
  CROSSJOIN(
    {[Period].[Jan], [Period].[Dec], [Period].[Sep]},
    CROSSJOIN(
      {[Entity].[BE08008309], [Entity].[BTSEMEALA]},
      CROSSJOIN(
        {[Years].[2018], [Years].[2017], [Years].[2014]},
        CROSSJOIN(
          {[ICP].[ICP]},
          CROSSJOIN(
            {[Currency].[USD]},
            CROSSJOIN(
              {[Custom1].[TOPC1]},
              CROSSJOIN(
                {[Custom2].[TOPC2]},
                CROSSJOIN(
                  {[Custom3].[TOPC3]},
                  {[Scenario].[Actual], [Scenario].[June Forecast]} -- Replace with your full Scenario members
                )
              )
            )
          )
        )
      )
    )
  ) ON ROWS

Even Better: Use Essbase's Shorthand for Crossjoins #

Essbase lets you use the * operator as a shorthand for CROSSJOIN, which makes your query way more concise and readable. This does the exact same Cartesian product as the nested version:

SELECT 
  {([Version].[FINAL])} ON COLUMNS,
  {[Period].[Jan], [Period].[Dec], [Period].[Sep]} *
  {[Entity].[BE08008309], [Entity].[BTSEMEALA]} *
  {[Years].[2018], [Years].[2017], [Years].[2014]} *
  {[ICP].[ICP]} *
  {[Currency].[USD]} *
  {[Custom1].[TOPC1]} *
  {[Custom2].[TOPC2]} *
  {[Custom3].[TOPC3]} *
  {[Scenario].[Actual], [Scenario].[YourMissingMember]} ON ROWS

Key Tips for New MDX/Essbase Users #

• Finish your member sets: Always close your braces and complete member references (your original query cut off at [Scenario].[Jun...—Essbase will throw an error if you leave this incomplete).
• Watch performance: A Cartesian product across many dimensions can create a huge number of rows. If your query runs slow, try filtering members down to only what you need (e.g., use FILTER or pre-built member hierarchies).
• Double-check member names: Essbase is often case-sensitive, so make sure your member references match exactly what's in your cube.
